What are Potato Beetles?

Before we answer the question at hand, let's first talk about what potato beetles are. The potato beetle, also known as the Colorado potato beetle, is a small beetle that is native to North America.

These beetles are known for being a major pest of potatoes, but they may also feed on other plants.

While potato beetles prefer to feast on potatoes, they will happily munch on tomato plants as well. They will eat the leaves, stems, and even the fruit itself. If left unchecked, potato beetles can quickly decimate a tomato plant and ruin your harvest.

Row Covers: Covering your tomato plants with a fine mesh or fabric can help prevent potato beetles from accessing them in the first place. This is a good option for gardeners who are dealing with persistent infestations.

Whichever method you choose, it's important to stay vigilant when it comes to potato beetles. These pests can quickly reproduce and spread, so it's important to take action as soon as you notice any signs of damage.
